If the cause of the alarm still exist, however, the alarm will resume, ・ The overcurrent alarm will automatically reset when the cause of the alarm is removed. NOTE ・ When message [*ALARM* EXT] has appeared indicationg that an external alarm is aplied, remove the alarm status of the external device which is sending the alarm signal via the external control connector (J1) and then rest the Electronic Load from the alarm status. ・ The alarm output ternimal is at the external control connector (J2) on the rear panel. The alarm signal deliverd through this ternimal is as shown in Figure 3.5-10. ・ When the alarm is reset after Over-voltage, Overheat, Fuse blown out or Alarm detected appears two times or more continuously, the PSET value is at 0.0W. 3.5.11 Short Function If you press the 【 SHIFT】＋【SW】 (SHORT) keys, the Electronic Loadies automatically set to the maximum current (if it is in the C.C mode) or to the minimum resistance (if it is in the C.R mode). When in this state, if the DC input terminal voltage becomes lower than 1.5V, the Short signal output terminals of the external control connenctor (J2) on the rear panel will deliver a 'make' contact signal. You may use this contact signal to drive a larger relay to short the DC input terminals as shown in Figure 3.5-11. The operating input range of the Electronic Load in 1.5V or higher. You may use the Short function, for example, to test the droop characteristics of a regulated DC power supply at a range lower than 1.5V.

Page 93 Chapter 3. OPERATING METHOD • When in this mode of remote control operation, the current drawn by the Electronic Load NOTE is the sum of the remote-controlled current proportional to the voltage signal plus the local-controlled current (I SET value) set from the front panel. On the front panel dis- play, the local-controlled current alone is displayed.
Page 94: Analog Remote Control Of C.r Mode
Chapter 3. OPERATING METHOD • For resistor Rin, use a quality resistor of good stability against temperature change and NOTE aging. If you are using a potentiometer, use a one whose residual resistance is less than 300 ohms. The recommended types of resistors are as follows: Wire wound resistors Metallic film resistors Vernier potentiometers.

Chapter 3. OPERATING METHOD 3.7.6 Trigger Signals The Electronic Load delivers a trigger signal and accepts a trigger signal. You may use them for the follow- ing purposes: • Trigger output signal: For synchronization to view on an oscilloscope the waveforms of switching actions.
Page 101: Trigger Input Signal
Chapter 3. OPERATING METHOD [2] Trigger input signal The Electronic Load accepts a trigger input signal via pins ③ and ④ of J2 on the rear panel as shown in Figure 3.7-14. The allowable maximum voltage of the trigger input signal is 6 V and the acceptable minimum pulse width is 20 µs.
Page 102: Master/Slave Parallel Operation
• Up to five Electronic Loads of the same units can be connected in parallel. If you want to connect more than five units in parallel, consult your Kikusui agent. • Make the cabling distances (of flat cables and load cables) as short as possible. For the load cables, use sufficiently heavy cables and strand them to prevent noise.
Page 103 Chapter 3. OPERATING METHOD • As you set the SW1-1 of the slave unit to ON, message [<SLAVE>] will appear on its display indicating that the Electronic Loads are in the master/slave mode. The modedisplayed on a slave unit may differ from that on the master unit--this does not cause any trouble. The current value indicated on the display of a slave unit denotes the current being drawn by the slave unit itself--the values may differ among units slightly (several percent).
Page 104 Chapter 3. OPERATING METHOD Flat cables for parallel operation When laying flat cables, be sure to provide strain relief as shown in Figure 3.8-2 and make the pin layout as follows: (P1) (P2) No. 1 ---------- No. 1 No. 2 ---------- No. 2 •...
Page 105 Chapter 3. OPERATING METHOD ＡＰＰＥＮＤＩＸ ■ ■ ■ ■ ■ Ammeter calibration for master/slave parallel operation The Electronic Loads are shipped after calibrating their ammeters at vendor's factory. For parallel opera- tion, however, they can be calibrated more accurately in the state that they are actually setup and connected for the parallel operation.
